census/enumeration data
78541These data files provide population counts for racial
and ethnic groups living in all the jurisdictions of the states in
the United States in 1980. These data were produced as part of the
Census Bureau's commitment under Public Law 94-171 to aid states'
legislatures in the redistricting process. Public Law 171 of the
94th Congress was passed in 1975 to help facilitate the
one-man-one-vote concept enunciated in 1963. It specifies
procedures for conducting the decennial census for those states
wishing to participate and makes improvements for reporting
the findings as well. As a result of this law, the Census Bureau
was authorized to prepare for each state a data file that contains
population counts for racial and ethnic groups living in all the
jurisdictions of the state. Each of these files contains summary
statistics for seven population groups/types: Whites, Blacks,
American Indians, Eskimos and Aleuts, Asians and Pacific Islanders,
Spanish-Hispanics, total population, and population of other races.
Each record in each of the files is a type of census reporting area
arranged in hierarchical order. There are 51 data files, one for each
of the states plus one for Washington, DC. Each of the files has the
same format of 156-character logical records with characters 1-100
containing identification data and the alphabetic name of the record
and characters 101-156 containing the data for the seven population
groups/types. Data are provided for states or state equivalent,
counties or county equivalent, minor civil divisions (MCDs) or census
county divisions (CCDs), incorporated places, election precincts or
their equivalent (if any), census tracts or block numbering areas (BNAs)
(if any), and block groups and blocks in blocked areas, or enumeration
districts in nonblock-numbered areas. The Census Bureau has produced a
file, User Note No.#2 (Part 90), to accompany the PL94-171 series that
documents a problem encountered in all but nine states in the series.
The nine states NOT affected are Connecticut, Delaware, Hawaii, Maine,
Massachusetts, New Hampshire, New Jersey, Rhode Island, and Vermont.
The file contains a list of places split across counties or MCD/CCDs
that have two partial records but do not have a "part" indicator on
either record. Because of the omission of this part indicator, it is
not possible to connect the two parts of the same record (place) for
analysis purposes without the User Note No.#2 that allows researchers
to identify these places and use the data for them more easily. There
are 5,971 records (split places) in the file, each with a logical record
length of 48.
